RADIATOR.

VApplication led March 5, 1926. Serial No.'92,634.

rllhis invention relates to improvements in radiators and more particularly to superheated steam and water containing radiators and the objects of the invention are to simplify and improve the construction in such manner as to increase the eiliciency of the radiator withoutincreasing the cost thereof.

p Further objects are to provide a radiator so constructed with heating and air tubes whereby the air circulation is improved throughout the room or the like in which the radiator is located.

Still further objects are the provision of a` radiator of light weight, requiring less 5 volume of water and smaller mains and connections by making quicker circulation.

With these and other objects in view, the invention consists essentially of a plurality7 ofsteam or hot water tubes communicating with a suitably supportedhollow base and a head member and provided intermediate or between each pair of said tubesl with an air tube adapted to create an indirect draft whereby the cold air is drawn therethrough and heated, causing a quicker circulation of air throughout the room in which the radiator is situated. Y

Referring `now to the drawings, in which like characters of reference indicate corresponding parts in each figure:

Figure 1 isa side elevation of my improved radiator.

Figure 2 is a transverse section on the line 2-2 of Figure 1.

Figure 3 is an enlarged detail view showing construction of the heating 'pipes and the tortuous air tube.

Referring now more particularly to the drawings, in which a preferred'example of my invention is illust-rated, a hollow base l() is suitably supported on legs I] and 12 with pipe connections 13 and .i4 at either end secured in any well known manner to the base 10 by brazing or welding and is adapted to be connected with the heating circuit.

Communicating with the base are a plnrality of pipes 15 arranged in spaced relationship to one another and communicating at their upper ends with a hollow head member 16 whereby the circulation of hot water or super-heated steam is provided,

Within each of these hot water or heat radiating pipes 15 is an air tube 17 bent to form a tortuous passageway extending through the base l0 and head 16 and adapted not only to supply a heating surface but to create a. draft which draws up the' cold air from the bottom, increasing the circulation of air throughout the room or chamber in which the radiator is situated.

The tortuous passageway formed by bent air tubes 17 acts as a check 0n the current of air passing therethrough, and thus provides for more effective heating oi it.

From the foregoing it will be seen that the essential and novel features of my invention are the combination with the heating pipes, of a plurality of air tubes within each of said pipes and provided with air checking means therein to cause the air` passing therethrough to be more efficiently heated and thus increase the circulation.

As many changes could be made in the above construction, and many apparently widely different embodiments of my invention, within the scope of the claims, con

structed without departing from the spirit or scope thereof, it is intended that all inatter contained in the present specication and accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. Avradiator comprising a hollow head and a hollow base, a plurality of steam pipes in spaced relationship to one another connecting said head and base, a plurality of tortuous air tubes within said pipes extending through the base and the head to provide indirect passageways for the air whereby it is more readily Vheated by the steam pipes.

2. A radiator of the character described comprising a head portion and a. base portion, pipes connecting said oortions, suitably bent air tubes open at both ends extending within saidpipes to provide a tortuous passageway for a current oit air therethrough. In witness whereof I have hereunto set my hand.
